Acral persistent papular mucinosis is a subtype of the localized papular mucinosis. Clinically, ivory to flesh-colored papules develop exclusively on the back of the hands, the extensor surface of the wrists, and occasionally the distal forearms. Histologically, mucin accumulates in the upper reticular dermis, typically sparing a subepidermal zone and fibroblasts are not increased in number. On experiencing a case of numerous papules on both hands and forearms of a fifty year-old woman, we present it as acral persistent papular mucinosis.

Purpose: The electronic frailty index (eFI), which is derived from electronic health records, has been recommended as screening tool for frailty due to its accessibility and ease of use. The objective of this systematic review was to identify the prevalence of frailty assessed by the eFI and its influence on health outcomes in older adults with chronic diseases. Methods: We searched PubMed, Embase, Web of Science, CINAHL, SCOPUS, Cochrane, Google search, and nursing journals in Korean from January 2016 to December 2022. Results: Twelve studies were analyzed. The eFI score, based on routine clinical data, was associated with adverse health outcomes. The most frequent outcome studied was mortality, and the eFI was associated with increased mortality in nine studies. Other outcomes studied included hospitalization, length of stay, readmission, and institutionalization in relation to hospital care usage, and cardiovascular events, stroke, GI bleeding, falls, and instrumental activities of daily life as health conditions. Conclusion Early identification of frailty in older adults with chronic diseases can decrease the burden of disease and adverse health outcomes. The eFI has a good discriminative capacity to identify frail older adults with chronic diseases.

The aim of this study is to evaluate the effect of viscoelastic substance on corneal thickness, corneal endothelium and intraocular pressure by measuring corneal thickness, corneal endothelial cell density and intraocular pressure in extracapsular cataract extraction with posterior chamber lens implantation. The study comprised of 50 patients, divided into two groups: extracapsular cataract extraction with posterior chamber lens implantation using Healon(R) or 2% methylcellulose(Metrol(R)). The txtracapsular cataract extraction was done by irrigation and aspiration technique and the posterior chamber lens was implanted into posterior chamber. The corneal thickness and endothelial cell density were measured preoperatively and at 6 weeks of postoperative period: intraocular pressure was measured preoperatively and at 24 hours of postoperative preiod. The results were as follows: 1. The preoperative corneal thickness, endothelial cell density and intraocular pressure were 499 +/- 34 micrometer, 2523 +/- 388 cells/mm2 and 15.9 +/- 2.4mmHg in average respectively. 2. The postoperative corneal thickness with Healon(R) was 501 +/- 42 micrometer, and with Metrol(R) was 491 +/- 28 micrometer. There was no significant difference between Healon(R) used and Metrol(R) used group(p<0.05). 3. The loss of endothelial cell with Healon(R) was 10.7%, and with Metrol(R) was 17.1%. The endothelial cell loss was lower in Healon(R) used group than that of Metrol(R) group. 4. The intraocular pressure with Healon(R) was 14.6 +/- 3.9mmHg, and with Metrol(R) was 12.3 +/- 4.4mmHg. There was no significant difference between Healon(R)-used and Metrol(R)-used group(p<0.05).

PURPOSE: The aim of this study was to evaluate the utility of contrast-enhanced MRI with first-pass and delayed images in prediction of myocardial viability after acute myocardial infarction. MATERIALS AND METHODS: Ten patients (M:F=:4, mean age =6 5 years) with acute myocardial infarction underwent first-pass image after bolus injection of gadolinium (one image/sec for 120sec)and delayed image (7 2 minutes later). According to 60 segments on midventricular level, the assessment of MRI were concerned about location of lesion, depth of lesion, enhancement on first-pass image and enhancement pattern on delayed image. MRI findings were compared with wall motion on resting echocardiography and stress or follow-up echocardiography. RESULTS: 1) MRI findings were classified into 4 types: normal enhancement on first-pass and delayed images (type 1), normal enhancement on first-pass image and nontransmural hyperenhancement on delayed image (type 2), non-transmural enhancing defect on first-pass image and transmural enhancement with endocardial non-enhancing defect on delayed image (type 3), and transmural enhancing defect on first-pass image and transmural hyperenhancement on delayed image (type 4).2) Type 2 suggested viable myocardium and type 3 had high porbability of viability. Type was compatible with non-viable myocardium. CONCLUSION: Enhancing defect on first-pass image and involving thickness on both the first-pass image and delayed image in contrast enhanced MRI may predict myocardial viability.

Parkinsonism is a clinical syndrome presenting with bradykinesia, tremor, rigidity, and postural instability. Nonmotor symptoms have recently been included in the parkinsonian syndrome, which was traditionally associated with motor symptoms only. Various pathologically distinct and unrelated diseases have the same clinical manifestations as parkinsonism or parkinsonian syndrome. The etiologies of parkinsonism are classified as neurodegenerative diseases related to the accumulation of toxic protein molecules or diseases that are not neurodegenerative. The former class includes Parkinson’s disease (PD), multiple-system atrophy, progressive supranuclear palsy, and corticobasal degeneration. Over the past decade, clinical diagnostic criteria have been validated and updated to improve the accuracy of diagnosing these diseases. The latter class of disorders unrelated to neurodegenerative diseases are classified as secondary parkinsonism, and include drug-induced parkinsonism (DIP), vascular parkinsonism, and idiopathic normal-pressure hydrocephalus (iNPH). DIP and iNPH are regarded as reversible and treatable forms of parkinsonism. However, studies have suggested that the absence of protein accumulation in the nervous system as well as managing the underlying causes do not guarantee recovery. Here we review the differential diagnosis of PD and parkinsonism, mainly focusing on the clinical aspects. In addition, we describe recent updates to the clinical criteria of various disorders sharing clinical symptoms with parkinsonism.

BACKGROUND AND PURPOSE: We investigated subsequent vascular events in patients with transient ischemic attack (TIA) and determined the predictors of such events among vascular risk factors including large-artery disease, TIA-symptom duration, and acute ischemic lesions on diffusion-weighted imaging (DWI). METHODS: We identified 98 consecutive patients with TIA who visited a tertiary university hospital and underwent DWI and brain magnetic resonance angiography within 48 hours of symptom onset. We reviewed the medical records to assess the clinical characteristics of TIA, demographics, and the subsequent vascular events including acute ischemic stroke, TIA, and myocardial infarction. RESULTS: Large-artery disease was detected in 55 patients (56%). Ten patients (10%) experienced TIA symptoms for longer than 1 hour, and acute infarctions on DWI were identified in 30 patients (31%). During the mean follow-up period of 19 months, seven patients (7%) had an acute ischemic stroke and 20 patients (20%) had TIA. Retinal artery occlusion in two patients, spinal cord infarction in one patient, and peripheral vascular claudication in one patient were also recorded. Cox proportional-hazards multivariate analysis revealed that large-artery disease was an independent predictor of subsequent cerebral ischemia (hazard ratio [HR], 2.8; 95% confidence interval [CI], 1.1-7.1; p=0.02) and subsequent vascular events (HR, 2.9; 95% CI, 1.2-6.7; p=0.01). CONCLUSIONS: In patients with TIA, large-artery disease is an independent predictor of subsequent vascular events. Acute infarction on DWI and a symptom duration of more than 1 hour are not significantly correlated with a higher risk of subsequent vascular events. These findings suggest that the underlying vascular status is more important than symptom duration or acute ischemic lesion on DWI.

BACKGROUND: The autonomic nervous system plays a critical role in triggering ventricular arrhyhmia and sudden death early after acute myocardial infarction. This study was designed to determine whether or not vagal and sympathetic responses are impaired after myocardial infarction and to evaluate the utility of physiologic stress tests for assessing autonomic dysfunction after myocardial infarction. METHODS: 8 male patients with acute myocardial infarction(Group A) and old myocardial infarction(Group B) were studied with 8 control subjects of coinciding age and sex. 5 physiologic stress tests(deep breathing, sudden standing, Valsalva maneuver, ice bag application on the face, 70degrees headd-up tilt test) were performed. RESULTS: 1) Variation in heart rate during deep breathing, Standing-up, Valsalva maneuver, and ice bag application on the face was less in Group A than in Group B or Group C. 2) There was no significant difference in variation of heart rate between Group B and Group C. 3) Variation in heart rate caused by 70degrees tilt was not significantly different among the three groups. CONCLUSION: Early after myocardial infarction, parasympathetic responses were significantly impaired, whereas sympathetic responses remained intact. Heart rate variability using physiologic stress test may be provide a means of detecting autonomic dysfunction after acute myocardial infarction.

We evaluated the clinical results of 43 patients (47 eyes) who underwent cataract extraction and implantation of domestic posterior chamber intraocular lens manufactured by Universal Optics Co. (UNI(R) IOL) and could be followed up over 6 months. The mean follow-up period was 10.2 months with a range of 6 to 15 months. The results were as follows: 1. The final corrected visual acuity of 0.5 or better was noted in 41 eyes (87.2%). 2. The difference between the calculated postoperative refraction and the actual postoperative refraction was less than +/-1.00 D in 33 eyes (70.2%). 3. The corneal thickness increased 8.2% at postoperative period of 3 days and returned to preoperative level at postoperative period of 4 weeks. 4. The corneal endothelial cell density decreased 11.2% at postoperative period of 4 weeks and 12.8% at postoperative period of 6 months. 5. The early postoperative inflammatory reaction in anterior chamber and deposits on the surface of intraocular lens decreased gradually in the course of postoperative period. 6. The postoperative complications included posterior capsular opacification (7 eyes), fibrinous membrane (3 eyes), and hyphema (2 eyes). The above results showed that the visual outcome and the safety of UNI(R) IOL were favorable.

BACKGROUNG AND OBJECTIVES: The aim of this study was to analyze the influence of changes in ventricular preload and afterload, atrial and ventricular pacing on the coronary flow reserve (CFR). METHOD: Five open chest anesthetized dogs were studied in five sequential stages:baseline, saline solution volume loading (293.8+/-29.2 ml for 10 min), atrial and ventricular pacing (120, 140, and 160 bpm), and aortic clamp. Coronary blood flow (CBF) was measured with electro-magnetic flowmeter. CFR was defined as the ratio of hyperemic CBF (hCBF) to resting CBF (rCBF). Hyperemia was induced by IV adenosine infusion (1 mg/kg/min). RESULTS: 1)After volume loading wtih saline solution, CFR significantly decreased (p<0.05) because rCBF was increased while hCBF remained unchanged. 2)Atrial pacing produced increase in rCBF but did not change hCBF. Consequently CFR singificantly reduced when heart rate (HR) increased from sinus rhythm to 120, 140, and 160 bpm (p<0.01). 3)Ventricular pacing produced decrease in hCBF but did not change rCBF. Consequently CFR significantly reduced as HR increased from sinus rhythm to 120 (p<0.05) , 140 (p<0.01), and 160 (p<0.01) bpm. 4)After aortic clamp, CFR significantly decreased (p<0.01) because rCBF increased while hCBF remained unchanged. CONCLUSION: We found that CFR is dependent on the changes in volume loading, HR, and ventricular afterload that may commonly occur in clinical situations.
